Hello! I am running into an issue with my new SFF build where immediately after sustained workloads, the PC will either freeze or completely turn off. I wasn't sure what the issues were at first so I tried different software to try to isolate it. I first started having this issue in games. I don't play any heavy titles, just Valorant and League of Legends, so I thought this behavior was very odd. I also had accidentally bent the CPU pins before, but bent them back. The CPU goes into the socket easily still but I know there's still a chance that it isn't working properly. My average temperature is ~35 degrees C idle and ~73 degrees C on load for my CPU and ~38 degrees C idle and ~76 degrees C on load for my GPU. At this point, I'm 60% sure it's the CPU and 40% sure its the PSU but I would like a second, third, fourth... and so on... opinion. Thanks in advanced!

 

Steps Taken:

cleared CMOS, ran at stock settings -- > freeze/shutdown

heaven benchmark for 2 hours to isolate GPU --> No issues

3D Mark Time Spy benchmark --> No issue

3D Mark Stress test --> 99% and 98.8% --> immediately crashes after. Frozen screen/immediate shutdown

Memtest86 --> No issue 0 errors

Flashed most recent BIOS --> freezing/shutdown after sustained load

Reinstalled windows --> freezing/shutdown after sustained load

Rearranged fans in case --> freezing/shutdown after sustained load

Unplugged and reseated power cables into motherboard --> freezing/shutdown after sustained load

 

I have a 700W power supply coming in on Sunday so I hope that may fix the issue.

I think the PSU might be the issue here?Have you done any kind of OC?

As far I've seen that the RTX 3000 series have momentary spikes in power draws under sustained load which causes the PSU to trip.. That MIGHT be the issue here too..?

That's also what I was thinking but itf the PSU were to trip, it would completely shut down the system instead of freezing would it not? Still not sure how its able to maintain 100% load for so long but only trip or freeze when the task is shut down after the task is complete. Also, no OC. Everything stock except the RAM to run at its rated speed. I forgot to include it, but even at stock settings for RAM running at 2133 Mhz, CPU running at 3.9 Ghz, and GPU running at 1700 Mhz, the PC still shuts off or freezes.

It wasn't inherently my fault. AMD's CPU mounting method to their motherboards is 100% inferior to intel's. With a little suction that CPU is coming out whether you want it to or not. ;(

Is that the new stock of corsair SF or the old one? The old one had some issues i think.

I bought it recently. Its an SF600 and if the thing that I read online is true, it was manufactured on the 29th week of 2020 ¯\_(ツ)_/¯

Update: Just put in an 800w SFX L PSU hoping to fix my issue but could not complete 3DMark Time Spy stress test without computer freezing. Tried to run Furmark CPU Burner, ran fine for 30 minutes and as soon as hit Stop computer shuts off. 90% sure its a because of the bent pins on the CPU.
